BRICK AND VTILE IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 252,636, dated January24, 1882. Application filed November 19, 1851. (No model.) Patented inCanada March 13, 1880.

To all Iwhom it may concern Be it known that I, AUGUSTUS VEHLANN, acitizen ofthe Dominion of Canada, residing at Aldborough, in the countyof Elgin and Province of Ontario, have invented certain new and usefulImllrovements in Brick and Tile Machines; and I do hereby declare thatthe following is a full, clear, and exact description ofthe same,reference being` had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a sectional view of a machine constructed inaccordance with my invention, and showing the cutting table or carriagein elevation. Fig. 2 is a top plan view of the hollow base. Fig. 3 isahorizontal section thereof, and Fig. 4 is a perspective view oftheadjustable cutting table or carriage.

The present invention has relation to certain new and usefulimprovements in brick and tile machines; and the objects thereof are toccnstruct a machine that will prove strong and ldurable and effective inits operation as well as easily operated and not liabfe to get out oforder, also insuring the perfect and effectual working of the clay andthe producing ot the brick or tileuith comparatively little labor andtrouble and with little or no waste ot' the clay. These several objectsI attain by the construction, substantially as shown in the drawings andhereinafter described.

In the accom panyingdrawings, A represents an upright hollow cylinder,which may either be constructed in a single piece of metal or of twoseparate sections, as shown, and afterward bolted or otherwise connectedtogether. At the top of the cylinder A is an arch or bail, a, passingdiametrically across the opening in the cylinder and having its endsrigidly connected to the rim thereof. Through the arch or bail a passesa square-formed shaft, b, having connected to, it above and below thearch or'bail by suitable set-screws, c, collars d. The shaft b extendsdown and through the cylinder A, and has connected to it by set-screws ca series of knives or cutters, B. In place of being formed of cast-iron,the shaft is coilstructed of wrought-iron, thereby obtaining greaterstrength and durability.

The knives or cutters B, as will be sten, are

double instead of single, and have a square hole through their center toadmit of their being slipped over the end of the shalt b, and held inposition thereon by the set-screw e, as heretofore described. Thisenables the knives or entiers to be removed when required or adjusted onthe shaft to vary the distance. between them when a. greater or lessnumber is used, the setescrews being much more effi ctivc in connectionwith the square form ot' shalt than the ordinary keys now in use.

A sleevtf, may be employed to fit within the opening in the arch or baila, which opening is ofcircular form, or round, while the opening in thesleeve is vsquare to conform lo the shape of the shaft b, and a similarsleeve, g, near the lower end ot' the shaft, said sleeves serving' asjournals, thus enabling them to be removed when worn and replaced byothers.

The upright c vlinder A is connected in any suitable manner to a hollowbase, O, into which the lower end of the shaft b projects, and is formedwith a short journal, 7L, resting in' a step, i, at the bottom of thehollow base.

The sleeve g has its bearing in a erosspiece, 7c, which forms a pait ofthe top of the hollow base G, and below this sleeve the shaft b passesthrough a rectangular/cap or plate, t. This plate covers au opening inthe top of a plua ger, D, located within the hollow base C, and operatedby an eccentric, E, rigidly connected to the shaft b, its peripherybearing upon the faces of friction-rollers F, journaled within theplunger, as shown in Figs. 1 and 3. The plunger D forces alternately theclay through suitable molds, G, removably connected to doors Il, hingedto each end of the hollow base (l.

To admitof the plunger D moving backward and forward within the hollowbase O, it is formed7 with an elongated opening, m, through which theshaft b passes, said opening being covered by the plate or cap l, asbefore described, so as to prevent the clay from getting into theinterior of the plunger and affecting the working parts ofthe machine.The eccentric E, which is of cast-iron, revolves against the f1iction-rollers F, which causes the plunger D to have imparted to it. ahorizontally-reciprocating motion to force the clay ont through themolds in forming the brick or tile.

The above-described means of opera-ting the IOO plunger is considered ofgreat importance, as the crank ordinarily in use for this purpose worksagainst the side of the plunger, and the wrist of said crank necessarilywears very rapidly and lessens the quantity of clay pushed or forced outat each stroke, whereas the eccentric E gives both uniformity in motion,quantity of clay expressed, and lightness of draft. The doors II, aswill be seen. are hinged instead of being bolted, thereby facilitatingthe Y operation ot' changing the molds, and each doorat its top has awater tap or taps, a, for the puipose of giving ,a suiicient supply ot'water to each mold in use, thereby obviating the necessity ot' havingthe base of the machine on a water-level.

The plunger D at each end is provided with two valves` o, to admit airon its receding motion, and the molds G, when found necessary, areprovided with perfbrating-bolts p, connected to cross-bars q.

To each end of the hollow base C is connerted a cutting table orcarriage; but in the drawings I have simply shown one suoli, which isconsidered soffici' nt to describe 'their construction.

The table proper, as represented at I-or in other words, a carriage-isprovided with suitable truck or grooved wheels, r, which rideupon trackss, secured Ato a frame, K, connected in any suitable manner to the endof the hollow base C. The carriagel has connected to the sides thereofa. series of horizontal rollers,t, arranged parallel with each other,which together form the bed ot' the carriage to receive the clay. Thecarriage I is provided with a pivoted stop, L, so as to prevent the clayfrom being pushed too t'ar beyond the eutting-wires u, thereby renderingit unnecessary to return portions of brick or tile to the ma chine to bewrought over again. The wires u pass between the rollers t, and areconnected at their upper end to a horizontal bar, w, and

]. In a brick or tile machine, the square shaft b, passing throughcorrespondinglyformed openings in journals f g, at the upper and lowerends thereot',and having removably and adjustably connected to it theknives or cutters B, the same having square openings through which theshaft passes, and held thereon by set-screws e, substantially as and forthe purpose set forth.

2. Ina brick or tile machine, the combination, with the shaft b,carrying knives or eutters B, and eccentric E, of the plunger D,provided with friction-rollers F, and valves 0,substautially as and t'orthe purpose specified.

3. In a brick or lile machine, the plunger D, having air-valves o,elongated opening m, and friction-rollers F, in combination with theshaft b, carrying eccentric E, and the cap or plate l, substantially asand for the purpose set forth.

4. In a brick or tile inachine,the cylinderA, shaft b, knives or cuttersB, eccentric E, in combination with the hollow base C, provided withhinged doors H and molds G, and the plunger D, constructed as described,and having the friction-rollers F, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my nalnein the presence of two witnesses.

AUGUSTUS WEHLANN.
